Water bloom polluted water body remediation method
The invention discloses a water bloom polluted water body remediation method which comprises the following steps: enriching and intercepting blue-green algae through a soft enclosure, enabling the blue-green algae to enter an enrichment area, and suspending and putting a phosphorus removal material in the enrichment area; floating algae cells in the enrichment area are sucked into a bypass algae cell flocculation area, a magnetic flocculant is added into the polluted water body in the flocculation area, after stirring, magnetic mixture flocs formed by the algae cells are subjected to in-situ precipitation, the precipitated flocs are sucked out through a bottom suction pipe for dehydration and then subjected to follow-up treatment, and the treated water returns to a downstream remediation area of the original polluted water body; a lake purifier is arranged in the downstream remediation area as a core, emergent aquatic plants are planted in an auxiliary mode, nitrogen, phosphorus and carbon removal is achieved, the combined action of physical, chemical and biological methods is utilized, the blue-green algae is removed, the nitrogen and phosphorus concentration of a water body is reduced, meanwhile, bottom mud pollution is reduced, secondary outbreak of the blue-green algae is restrained, the cost is low, and the blue-green algae removal rate is high.
本发明公开了一种水华污染水体修复方法，包括以下步骤：通过软围隔富集、拦截蓝藻，使蓝藻进入富集区域，在富集区域悬挂投放除磷材料；将富集区上浮藻细胞吸入旁路藻细胞絮凝区，向絮凝区的污染水体中投加磁性絮凝剂，经过搅拌后，藻细胞形成的磁性混合物絮团原位沉淀，沉淀的絮团经底部吸管吸出脱水再进行后续处理，处理后的水回到原污染水体下游修复区；下游修复区设置以湖泊净化器为核心，辅以种植挺水植物，实现脱氮除磷和除碳，本发明利用物理、化学、生物方法的共同作用，在去除蓝藻、降低水体氮磷浓度的同时既减少了底泥污染，又抑制了蓝藻的二次爆发，成本低，蓝藻去除率高。
